Vintage Soft Beige Thick Cashmere Cardigan

This vintage cashmere sweater is VERY thick and soft, unlike most of the cashmere sweaters on the market today. I have never come across anything like it. The tag indicates medium, but it fits small. P to P 19.5" Shoulder across the back 13.5" It is marked on the tag as "Irregular". On the back, around waist level on the right there is a section where the weave is not done properly. I have included several photos. From a distance, you cannot see this flaw. I took several pictures from varying distances. Up very close it looks obvious, but from a regular distance, it's hardly noticeable. Made in USA.
